{"apiVersion":"1.0","identifier":"CVE-2026-82241","description":"Budibase backend-core (@budibase/backend-core, as used by @budibase/server) omits the shared address space range 100.64.0.0/10 from its default SSRF blacklist (DEFAULT_BLACKLIST) used by REST datasource query previews. When the default blacklist is active (i.e., a self-hosted deployment has not defined BLACKLIST_IPS), an authenticated user with the Builder permission can submit a REST datasource query preview request to POST /api/queries/preview targeting a reachable HTTP(S) service in the 100.64.0.0/10 range, causing the server to send a request to that target and return its response through the preview flow. Per the advisory, no released fix was identified at the time of publication; remediation is to add 100.64.0.0/10 to DEFAULT_BLACKLIST.","publishedAt":"2026-08-28T12:16:34","lastModifiedAt":"2026-08-28T16:18:32","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-82241","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","epssProbability":0,"riskScore":0.71,"affectedProduct":"Budibase","affectedVersions":"unknown","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-82241","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-82241","en":"https://www.redsauce.net/en/cves/CVE-2026-82241","fr":"https://www.redsauce.net/fr/cves/CVE-2026-82241","pt":"https://www.redsauce.net/pt/cves/CVE-2026-82241","de":"https://www.redsauce.net/de/cves/CVE-2026-82241","sk":"https://www.redsauce.net/sk/cves/CVE-2026-82241","el":"https://www.redsauce.net/el/cves/CVE-2026-82241"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-82241"}}
